Nidec Shares Experience Significant Decline Following Accounting Probe Announcement
Nidec Corp. (6594.T) shares saw a substantial reduction in value, plunging as much as 22% on Thursday, September 3, 2025, before paring some losses to close down 19% at ¥2,531. The dramatic decline was primarily fueled by the company's announcement that it would establish a third-party committee to investigate potential incidents of improper accounting.
The Event in Detail: Accounting Probe and Financial Delays
The market's sharp reaction was directly linked to Nidec's disclosure of an internal probe that uncovered documents suggesting potential improper accounting practices by the company and its group entities, possibly with management involvement. This investigation centers on a payment of approximately ¥200 million (about $1.4 million) by a Chinese subsidiary. The gravity of the situation has led to significant operational and financial disruptions for the Kyoto-based manufacturer.
Specifically, the ongoing investigations have necessitated the delay of Nidec's fiscal year 2025 annual report until September 26, 2025. Furthermore, the disclosure of financial results for the first quarter of fiscal year 2026 has also been postponed. These delays stem from broader inquiries into trade transactions and customs issues involving a consolidated subsidiary, with a customs scandal at its Italian subsidiary potentially incurring penalties ranging from $32 million to $224 million.
Analysis of Market Reaction: Governance Concerns vs. Fundamental Value
The considerable plunge in Nidec's stock price occurred despite a generally positive sentiment in the broader Tokyo market on the day, where Japanese stocks were broadly higher, led by technology companies. This divergence highlights the market's acute sensitivity to corporate governance issues. Investors rapidly re-evaluated the risk profile of Nidec in light of the potential accounting irregularities, overshadowing the company's strategic focus on high-growth segments like electric vehicle (EV) components and advanced motor solutions for data centers.
While the market responded with concern, some analyses suggest a potential undervaluation. Simply Wall St, for instance, calculated an intrinsic fair value of ¥3,313 per share, indicating a 25.3% discount at the time of the initial decline. A subsequent report on September 9, 2025, reiterated this, stating Nidec appeared significantly undervalued by 31.6% relative to an estimated fair value of ¥3,617.5. Nidec's current Price-to-Earnings (P/E) ratio stands at 18.04, which is above the Electrical industry average of 12.9x, but notably below its proprietary "Fair Ratio" of 27.7x, suggesting the market may not fully reflect its future potential.
Broader Context and Implications: Strategic Shifts and Long-Term Performance
Nidec's recent stock decline adds to a pattern of long-term underperformance, with shares down nearly 47% over the past five years and 12% year-to-date. This event underscores persistent concerns about corporate governance within Japanese corporations, particularly those with extensive global operations.
Despite these challenges, Nidec has been actively pursuing a strategic turnaround, emphasizing cost optimization, supply chain diversification, and innovation. The company reported record-high consolidated net sales of ¥2,607,094 million (up 11.1% year-on-year) and operating profit of ¥240,200 million (up 48.4%) for the fiscal year ended March 31, 2025. Key growth drivers include automotive products, particularly electric power steering motors, and small precision motors for high-value-added near-line HDDs in data centers and water-cooling modules for AI servers. While Q4 2025 revenue grew 9.8% year-on-year to ¥661.13 billion, driven by these areas, a Q2 2025 earnings miss highlighted the risks of overreliance on the EV sector.
Third-party analyses present a mixed but largely optimistic view on Nidec's intrinsic value. A consensus of 17 analysts holds a "BUY" recommendation for Nidec (JP:6594), with an average target price of ¥3,570.62. Price targets range from a low of ¥2,600 to a high of ¥4,800. For its ADR (NJDCY), one analyst projects an average target of $4.66, implying a 5.8% growth from the September 17, 2025 price of $4.40. Notably, Zacks Research upgraded its rating to "Hold" on September 15, 2025, and Wall Street Zen upgraded to a "Strong Buy" on August 23, 2025, reflecting a belief in the company's underlying value.
"The alignment between analyst consensus and Simply Wall St's valuation is notable... both suggesting that the stock is currently undervalued and possesses upside potential."
Looking Ahead: Investigations and Strategic Execution
The immediate future for Nidec will be largely dictated by the findings of the third-party investigation into accounting irregularities and the resolution of customs issues. The successful communication of these outcomes and the restatement of delayed financial reports will be crucial in restoring investor confidence. In the longer term, Nidec's strategic goals include achieving an operating profit of ¥350 billion by fiscal 2028 and consolidated sales of ¥10 trillion by 2030, with a significant portion expected from organic growth in high-margin segments like industrial equipment and EV components, alongside new M&A activities. The market will closely monitor the company's ability to execute these strategic shifts while navigating ongoing governance challenges and geopolitical uncertainties, especially concerning its supply chain and international operations.
